WATER-JET FOR AMALGAMATlNG-MACHINES.

I Application tiled November 23, 1893. Serialflo. 191,755. (No model.) I

To all whom it may concern.-

Be it known that I, ARTHUR W. ROBINSON, a citizen of the United States,and a resident of Milwaukee, in the county of Milwaukee and State ofWisconsin, have invented certain new and useful Improvements inWater-Jets. of Amalgamating-Machines, of which the folmoved by theaction of the jets of water either toward the tailings end of theamalgamator,

or may be caused to circulate around or partially around the amalgamatoraccording to the adjustment of the water jets. Thus the duration of theretention of the sand or gold bearing material within the amalgamatorand the degree of its agitation and consequent frequency of contact withthe steps of the amalgamator may be exactly regulated to secure the bestresults, and the process of separating the gold from the refuse may beadjusted, so as to secure the greatest possible speed. Consequently themachine can be quickly and without expense, put in condition to operatemost successfully and economically upon gold bearing materials ofdifiering qualities and characteristics. I

The invention generally stated comprises a tube or nipple set in theforce water pipe of the machine, which projects somewhat above its uppersurface. A small globe or spherically shaped piece of metal, which has ahole through it, rests on the upper-end of the tube (it may have a seaton the tube if desired) and it is held in place by a-threaded nut, whichengages with the thread on the nipple and an inwardly projectingcircumferential flange on the nut embraces the globe above itshorizontal zone, so that when the nut is loosened, a piece of wire orsimilar utensil may be inserted in the hole in the globe, and it (theglobe) thus easily and quickly turned and adjusted, so that it willdirect the water which comes through it in the desired direction; thenut being then screwed down again will grasp the globe and hold itfirmly in the desired position. Inasmuch as the globular adjustable jetpieces project slightly above the surface of the trough or force waterpipe,

a considerable quantity of sand will precipitate between them and remainpractically un disturbed. In order to raise this sand,intermediate holesare drilled in the trough or force water pipe between the adjustable jetpieces. These holes are necessarily constant in their direction butthere is sufficient control of the action of the machine secured, if

half of the jet pieces are adj ustable,

In the drawings hereof, Figure 1, illustrates a vertical sectional viewof the trough or valley bottom of an amalgamator machine, showing themercury deposit trough, the force water trough or pipe, the sand guardplates and the adjustable water jet pieces, which latter are the subjectof this invention. Fig. 2, illustrates a longitudinal vertical sectionof the parts as shown in Fig. 1, reduced in size and partly broken away.Fig. 3, illustrates a detail of the adjustable water jet pieces.

A, A are lines which indicate the sides of the valley of theamalgamator.

B is the mercury deposit trough.

O is the force water pipe.

D are the nipples screwed into the pipe 0.

E are the globular metallic jet pieces.

F are the nuts.

G are the flanges on the nuts which engage with the globular jet piecesand hold them in position when screwed down upon them.

H, Hare the sand guard plates.

I are the holes in the pipe 0 intermediate the adjustable water jetpieces.

Special attention is called to the peculiar construction of the jetpieces and co-acting parts; 2'. e., the nipples are truly cylindricaland threaded from end to end. This is the most simple and cheap form.Also the jet pieces F are not, or rather, need not be, of greaterdiameter than that of the nipples and they are provided with holes whichpreferably taper somewhat, but their larger end which is adjacent to thenipple is of considerably less diameter, than the hole through thenipple. Consequently it may describe a circle of such size as necessaryand it will always/fall within the circle of the bore of the nipple.Thus there will always be. unobstructed water supply for the jet pieces,and furthermore, the nuts which clamp the jet pieces to the nipple-likedevices are exceedingly simple in construction, and very inexpensive.These advantages have never before been attained, as I attain them, sofar as I know.

I have shown in the drawings a form ofconstruction of the parts as theyare made by me in actual manufacture, and it is a very good form; but Iwish it to be understood that al terations may be made in the details ofconstruction of the devices, particularly that the parts E need not beexact spheres, nor need they engage with a nipple, so called; a threadedboss on the pipe 0 may take the place of the nipples.

I claim- 1. The combination of a force water pipe, a hollow nipple-likedevice connecting with the interior of the pipe, a perforatedsubstantially spherical jet piece having its seat upon the upper end ofthe nipple and provided with a hole, the diameter of which is less thanthe interior bore of the nipple, and a threaded. nut which overlaps thejet piece, substantially as set forth.

2. The combination in an amalgamator of a force water pipe located inthe valley of the amalgamator, and having a series of holes on its upperpart, a series of hollow nipple-like devices connecting with theinterior of the pipe, located between the holes therein and perforatedjet pieces seated upon the upper ends of the nipples and having holesthrough them of less diameter than the bore of the nipples, and nutswhich screw upon the nip ples, and overlap the jet pieces, substantiallyas set forth.-

3. The combination of a water pipe, hollow nipple-like devicesconnecting with the interior of the pipe, jet pieces adapted to rest andbe seated upon the upper ends of the nipplelike devices vand. having atapering hole through them, the larger end of which is of less diameterthan that through the nipplelike devices, and a nut to clamp the jetpieces upon the end of the nipple-like devices, substantially as setforth.

Signed at Milwaukee, in the county of Mil- Waukee and State ofWisconsin, this 8th day of November, A. D. 1893.
